The B60-90-0589 is an FAA-PMA Laminated Member, Lateral (MGB) from the SKF B60-90 PMA family, approved by the FAA as a replacement for the Airbus Helicopters part 704A33-633-153 / 704A33633153 on the H125 / AS350 / H130 / AS355 models listed below.
From SKF to KRS: same part, same PMA, same Elgin plant
This part was developed and FAA-approved as an SKF Aerospace PMA – that is why it carries the SKF B60-90 part number. The approval, PMA No. PQ2457CE, belongs to the elastomeric operation at 900 N State Street, Elgin, Illinois, the site that held it as SKF Aerospace Sealing Solutions.
In January 2026 SKF completed the sale of its Elgin aerospace operation – its precision elastomeric devices business – to Carco PRP Group. The plant now operates as KRS Aerospace Elastomeric Solutions, and the FAA record lists KRS as the current PMA holder. Same part number, same PMA approval, same Elgin site – under a new owner.
According to SKF, its B60-90 PMA parts share the design and materials of the parts SKF supplies to Airbus Helicopters. The difference is the release path: FAA-PMA with an FAA Form 8130-3 instead of the Airbus part number.

FAQ
Is B60-90-0589 approved to replace Airbus 704A33-633-153?
Yes. The FAA PMA record for B60-90-0589 lists 704A33633153 as the approved replacement part number, for the models above. You can check it yourself on drs.faa.gov (Parts Manufacturer Approvals, PMA part number B60-90-0589). Always confirm installation eligibility against your approved maintenance data.
Why does the FAA record say KRS and not SKF?
SKF sold its Elgin, IL aerospace elastomeric operation to Carco PRP Group in January 2026; it now operates as KRS Aerospace Elastomeric Solutions and holds the same PMA (PQ2457CE).
Which certificate comes with the part?
FAA Form 8130-3. An EASA Form 1 is not available for PMA parts.
Is it accepted outside the United States (EASA, ANAC)?
Acceptance of FAA-PMA parts depends on the bilateral agreement with the FAA and on the operator's approved data. Check with your authority or CAMO before installation.

About KRS Aerospace Elastomeric Solutions
KRS Aerospace Elastomeric Solutions (Elgin, Illinois) traces its heritage to Chicago Rawhide, an American company founded in Chicago in 1878 that grew into one of the best-known names in seals and, later, aerospace elastomeric and vibration-control products from its base in Elgin.
SKF acquired Chicago Rawhide in 1990, and the Elgin site became SKF's aerospace elastomeric and sealing operation – the holder of FAA PMA PQ2457CE, first as SKF Aerospace Sealing Solutions. In January 2026 SKF completed the sale of this operation to Carco PRP Group, and it now operates as KRS, manufacturing elastomeric bearings, vibration isolators and engine mounts, dampers and molded rubber products for rotorcraft and other aerospace and defense platforms. The PMA approvals, part numbers and plant stayed the same.
